  Q: How to replace the Transmission Oil Cooler Hose on Chevrolet Astro?

  A:

  Vehicle elevation is the first step when replacing the transmission fluid cooler hose or pipe. Securely pull the plastic cap from quick connect fittings until it reaches about two inches beyond their original positions before removing oil cooler lines from the Radiator and transmission. A bent-tip screwdriver should be used to rotate and remove the retaining ring from the quick connect fitting for discarding. To remove a cooler line from the vehicle you should first let it fully extend from the connector while also removing all retaining rings (E-clips) linking the line to available quick connect fittings. Only new oil lines and fittings and retaining rings must be used for installation purposes. Follow this procedure to install the new retaining ring (E-clip): guide its half into one of the slots on the quick connect fitting and rotate it while ensuring the three clearance holes move through the slots without restriction. Each line of the cooler should receive a new plastic cap before installation and it is necessary to replace damaged caps. When installing cooler lines into the vehicle, users must place the end of the cooler line into the quick connect fitting until they hear or feel a click and should not place the plastic cap for installation. To verify proper fitting attachment pull the cooler line firmly backward before placing the plastic cap on the fitting without using your hand to depress the retaining ring and ensuring total fitting coverage without gaps with the yellow tube identification completely hidden inside. Place the final oil cooler line ends into both transmission and Radiator.
